Vintage completes Vali test with strong gas flow

The Vintage Energy Ltd. group in the southwest Cooper basin permit ATP 2021 has completed a successful 2-day flow test program at the Vali-1 ST1 well.

During the extended test, a flow rate of 4.3 million cu ft/d was measured through a 36/64-in. choke at a flowing well-head pressure of 942 psi.

Transient tests were taken before the extended flow test with recorded rates between 3.7 million cu ft/day (through a 24/64-in. choke at 1,676 psi) and 7.5 million cu ft/day (through a 32/64-in. choke at 1,593 psi). Gas samples were taken and are being analyzed.

All fracture stimulated zones contributed to the overall gas flow and there were rapid pressure build-ups during all shut-in periods with pressure levels quickly approaching 3,000 psi, said Neil Gibbins, managing director.

Estimated initial production flow rate for the well could be in excess of 5 MMcfd, he said.

All data will be assessed and incorporated into a field commercialization plan, including an estimate of the number of development wells required to efficiently produce gas and maximize returns.

Vali-1 ST1 will be completed with the installation of production tubing in October.

Discussions are underway with Cooper basin JV operator Santos for connection of Vali field to the Moomba gas gathering system.

Vintage is operator of the permit with 50% interest. Metgasco Ltd. and Bridgeport (Cooper basin) Pty Ltd. each hold 25%.
